Abstract: Abstract The packing conditions of unbound aggregate blends and porous asphalt mixture (PAM) are investigated via comparative studies between mechanistic laboratory measurements versus discrete element method (DEM) algorithmic simulations. Nine aggregate gradations with variations in… read more here.

DOI: 10.3390/ma15176060
Abstract: Compaction of hot mix asphalt (HMA) requires high temperatures in the range of 125 to 145 °C to ensure the fluidity of asphalt binder and, therefore, the workability of asphalt mixtures. The high temperatures are… read more here.
